What is the difference between these three CPUs?

[joelrh]

What is the differenct between the:

Athlon T-bird 1.2GHz/200
Athlon T-bird 1.2GHz/266
Athlon Palomino 1.2GHz MP

Anyone?

What does MP mean and why is the Athlon Palomino 1.2GHz MP more expensive than the Athlon T-bird 1.4GHz/200?

Thanks,
Joel

Ok , lets see ,the 1.2 /200T-bird is has a 200 mhz fsb bus and the 1.2/266 has a 266 mhz fsb , that is the only difference in these two processor , on the other hand ,the MP is for multiple processor setups and has a few extra instruction sets if I am not mistaken, therefore it outperforms the T-bird .The performance is'nt great enough for you to switch or pay the x-tra money from what I have read and any duron or T-bird will work in a multiple processor setup.

Chawken, did a good job explaining the MP processor in the following thread.

Here's a quote:

The Athlon 4 is the successor to Tbird
The Athlon 4 is code named Palomino and comes in 2 types, the Athlon 4 and the Athlon 4 MP. The MP incorporates Smart MP Technology - so as it functions in a dual processor board such as the Tyan Thunder K7 - and TLB (Translation Look-Aside Buffer). The Athlon 4 (Palomino) for desktop and mobile systems also has TLB and will have SSE1 and be a lower wattage chip.

As for the difference between the 200 and 266 version of the processor.

That is the FSB (front side bus). The 200 MHz FSB Tbirds were manufactured to be used primarily with 100 MHz SDRAM. (Although, they are also directly compatible with 200 MHz DDR (PC 1600 in DDR-speak.)

At the time of the release of the original TBird there were no motherboards that supported the 133 MHz SDRAM (and DDR wasn't available at all.)

With the release of the KT133A chipset, AMD released an updated 266 MHz (133 * 2) FSB version of the TBird CPU. These were known as Athlon-C processors. For all intents and purposes there is no difference between the 200 & 266 FSB version CPUs except for the multiplier.

For example, the 1200 MHz (200) Tbird uses a 12 multiplier. (12*100).
The 1200 MHz (266) uses a 9 multiplier. (9*133).

The 200 & 266 MHz FSB comes into play because AMD uses a DDR internal bus. This is also why AMD CPUs respond better to the increased bandwidth of DDR RAM.

If you are purchasing a new CPU+Motherboard combo you would do better purchasing a DDR based motherboard and 266 MHz version of the TBird.

266 MHz DDR (PC 2100) is at about the same pricepoint as 133 MHz SDRAM, but the performance is without a doubt much better.

I just have to compliment you Richard on the explanation , very well done.

Thanks wildone. Sometimes I get a bit carried away. :)

Very well done!

Some high school senior might steal that and use it for their English theme paper.
